Cisco IOS Releases and Images for the Cisco uBR7200 Series
12.3 BC Release Train Images and Requirements
The Cisco 12.3 BC release train is the latest Cisco IOS release train to support the Cisco uBR7200
Series, and emphasizes additional features and performance specifically for the Cisco uBR7246VXR
universal broadband router.
Table 1-2 displays the memory recommendations of the Cisco IOS feature sets for the
Cisco uBR7200 series universal broadband routers for Cisco IOS Release 12.3(9a)BC.
Cisco
uBR7200 series routers are only available with a 48 MB or 128 MB of Flash disk memory on the
I/O Controller cards. The UBR7200-NPE-G1 uses compact Flash disk only.
Note Flash disks, an alternative to linear Flash memory, are Flash memory-based devices that can be used as
file storage media in the PCMCIA card slots of the I/O Controllers. Each I/O Controller has two
PCMCIA slots and can be configured with up to 256 MB of Flash disk memory.
The image subset legend for Table 1-2 is as follows:
• i = IP routing, MPLS-VPN support, and non-cable interface bridging, including Network Address
Translation (NAT)
• k8 = DOCSIS Baseline Privacy
• p = IP routing with Intermediate System-to-Intermediate System (IS-IS) and Border Gateway
Protocol (BGP); MPLS-VPN support; no bridging and no NAT
• s = “Plus” features: NAT and Inter-Switch Link (ISL)
• k9 = 3DES level of encryption
Note All images support all of the hardware listed in the “Supported Hardware on the Cisco uBR7200 Series”
section on page 1-11, unless otherwise indicated.
Note A Cisco uBR7200 series router requires 256 MB of DRAM memory on the NPE processor card when
HCCP redundancy is configured and the router is supporting more than 3,000 cable modems. Using less
memory in these conditions results in temporary out-of-memory situations and incomplete
synchronization between the Working and Protect interfaces.
